0. J. McLENNAN. AGITATOR- FOR MIXED PAINTS.

No. 510,543. Patented Dec. 12, 1893 UNITED. STATES PATENT OFFICE.

CHARLES JOHN MOLENNAN, OF TORONTO, CANADA.

AGITATOR FOR MIXED PAINTS.

SPECIFICATION forming part of Letters Patent No. 510,543, dated December 12,1893.

Application filed December 2'7, 1892- Serial No. 456,343. (No model.)

To all whom it may concern:

Be it known that I, CHARLES JOHN MOLEN- NAN, master painter, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful. Improvements in Agitators for Mixed Paints, of which the following is a specification.

' My invention relates to improvements in agitators for mixed paints, which was the subject matter of a former application and the objects of the present invention are, first, to produce a simple means whereby the paint when mixed may be prevented from settling, and, secondly, to provide a means whereby the articles dipped may be kept from coming in contact with and thereby retarding the movement of the boaters and it consists essentially, first, of a. series of spirally twisted bars located at the bottom of the paint receptacle which form heaters and are driven by a chain of gear pinions, so that each adjacent bar rotates in the opposite direction, and, secondly, of a wire netting or frame supported slightly above the beaters.

The drawing represents a perspective view of a tank broken away so as to show my beaters and protection frame.

A, is the tank and, B, is aseries of spirally twisted bars each twist of which formsadouble beater, 12. Both ends of the beater bars,

B, are forged round so as to form spindles, b, on which the bars rotate in the bearing boards, 0, secured at the opposite ends of the tank.

D, D, are a chain of gearpinions, each pinion of which is placed on the spindle, b, and secured thereto.

E, is a sprocket pinion secured on the end of one of the beater bars, B, and connected by the sprocket chain, F, to the sprocket pinion, G, on the end of the driving spindle, H. The driving spindle, H, is journaled in bearings, I, secured on the end of the tank and has a pulley, J, secured at its outer end as shown.

It will be seen that upon the spindle, H, being caused to rotate the motion will be communicated to the chain of gearing D, so

that each adjacent bar will rotate in the opposite direction and thereby keep the sediment at the bottom of the tank completely 5o and being of small diameter they effectually cover the bottom and thus keep every part of the paint stirred or agitated there being no spaces of any consequence between the beaters not reached by them, which might occur were the heaters composed of larger spirals and of a less number of beaters.

My invention is more particularly designed for use in what is known as the dipping process of painting, and in order to prevent the articles being dipped from coming in contact with and thereby probably retarding the motion of the rotating heaters I preferably provide a frame of coarse wire netting, K, which I support upon the top edges of the end bearing bar, 0, and if necessary upon the edges of the side strips, C. The wire netting is of course placed only slightly above the heaters in order to protect them and also for the purpose of aflording the greatest possible room for dipping the articles.

-What I claim as my invention is 1. An agitator for mixed paints comprising a receptacle a series of elongated screw beaters of small diameter located in close proximity to and covering the entire bottom, with means for rotating said beaters, substantially as described.

2. An agitator for mixed paints comprising a receptacle,a series of elongated screw beaters of small diameter located in close proximity to the bottom thereof withmeans for rotating them, and an openwork protecting frame supported above said boaters but in close proximity thereto, substantially as described.
